WhatsApp for Motorola

This is a known quirk on Edge 50 series phones where Motorola's aggressive noise suppression over-processes the mic on WhatsApp audio. First make sure no case, screen protector, or finger is covering the bottom mic hole. Then check that WhatsApp has full microphone access in Settings > Apps > WhatsApp > Permissions > Microphone. To rule out the bottom mic, test a quick recording with a Bluetooth or wired headset. If the problem is only on WhatsApp, keep the app and the phone updated (Settings > System > System updates), since Motorola has shipped audio tuning patches, and report it through the Moto app feedback.

This is almost always battery optimization throttling WhatsApp in the background. Go to Settings > Apps > WhatsApp > Battery and set it to Unrestricted, then open Settings > Battery > Battery optimization, find WhatsApp and set it to Don't optimize; also turn off any aggressive power-saving or 'optimized charging' mode. Keeping the app whitelisted lets it hold a live connection so messages arrive instantly instead of only when you open the app. See how others solved this on Reddit

Motorola's aggressive battery management is usually the cause, so go to Settings > Apps > WhatsApp > App battery usage and set it to Unrestricted. Then open Settings > Battery and make sure Battery saver isn't on, and turn off Adaptive Battery if delays continue. Reboot the phone afterward so WhatsApp can re-establish its background connection.

This usually happens because the proximity sensor thinks the phone is near your ear, switching audio to the earpiece, or because WhatsApp lost access to the speaker. Open WhatsApp, play the voice note while holding the phone away from your face, and toggle the speaker; if it persists, go to Settings > Apps > WhatsApp > Permissions and confirm Microphone is allowed, then clear the WhatsApp cache under Settings > Apps > WhatsApp > Storage and restart the phone. Make sure WhatsApp is updated from the Play Store, since several voice-playback bugs on Razr 2024/2025 were resolved in newer app builds. See how others solved this on Reddit

This is usually the proximity sensor thinking the phone is near your ear, so audio routes to the earpiece instead of the loudspeaker. Hold the phone flat and away from your face when you tap play, and wipe the area around the front camera and the sensor at the top of the screen. Also press the volume-up key while a voice note is actually playing to confirm media volume isn't at zero. If it still happens, open Settings > Apps > WhatsApp > Storage & cache, tap Clear cache, and reboot. See how others solved this on Reddit

Motorola's aggressive battery optimization is the usual culprit, so go to Settings > Apps > WhatsApp > Battery and set it to Unrestricted (or Don't optimize). Then open Settings > Battery > Battery optimization, find WhatsApp and exclude it, and make sure Notifications are fully enabled under Settings > Apps > WhatsApp > Notifications. After that, reboot the phone so the changes take effect. See how others solved this on Reddit

This is almost always Motorola's aggressive battery optimization killing WhatsApp in the background. Go to Settings > Apps > WhatsApp > Battery and set it to Unrestricted (or Optimized off), then open Settings > Battery > Battery saver and make sure it isn't forcing background limits. Also disable any 'Sleeping apps' / Auto-launch restriction so the app can sync the moment a message arrives. See how others solved this on Reddit

The E13 ships with just 2GB of RAM, so WhatsApp competing with background apps is the usual cause of crashes and freezes. Clear WhatsApp's cache under Settings > Apps > WhatsApp > Storage & cache > Clear cache, force-close unused apps, and turn on Settings > System > Developer options > Don't keep activities is too aggressive, so instead reduce background load via Settings > Apps > See all apps and disable autostart for heavy apps. Keeping at least 1-2GB of internal storage free also noticeably reduces the random app crashes. See how others solved this on Reddit

HD sharing only works when both you and the recipient are on a recent WhatsApp build, so first update WhatsApp via the Play Store. When attaching an image, tap the HD button at the top of the photo preview and choose HD Quality before sending. You can also set the default: open WhatsApp > Settings > Storage and data > Media upload quality and set it to HD Quality. A weak or low-bandwidth connection can still force extra compression, so retry on stable Wi-Fi. See how others solved this on Reddit

Long WhatsApp video calls push the camera, modem, and screen together, so warming up is normal, but persistent heat is usually made worse by background apps and the always-on display. Lower the strain by going to Settings > Battery > Battery saver during long calls, dropping screen brightness, and removing any case while you talk. If the phone gets uncomfortably hot every time, clear WhatsApp's cache under Settings > Apps > WhatsApp > Storage & cache > Clear cache, then update WhatsApp from the Play Store.
